MAL-2026-11678

Summary: Malicious code in @or-sdk/bots (npm)

Details: npm/@or-sdk/bots is affected by the large-scale, self-propagating npm supply-chain worm of 2026-08-04 (the "Shai-Hulud: Here We Go Again" wave) — the same campaign that began with the compromise of the keyv and cacheable maintainer account. The listed version(s) were trojanized and republished by the worm after it reached an npm publish token belonging to a maintainer in this namespace; the payload enumerates every package a stolen token controls and republishes each with the same hook, so many packages under this scope were poisoned in the same short window. Every poisoned release adds a preinstall hook (`"preinstall": "node setup.mjs"`) that runs on a bare `npm install`, before any project code. setup.mjs downloads a standalone Bun runtime and runs a byte-identical, heavily obfuscated ~728 KB second-stage credential stealer (shipped as Math_Symbol.js / math_init.js). It harvests GitHub, npm, AWS, GCP, Azure, HashiCorp Vault and Kubernetes credentials plus generic secrets and private keys (TruffleHog-style sweep), reads CI/CD secrets and identifies build runners, then republishes further packages the stolen token can reach. Rather than a fixed command-and-control host, it exfiltrates stolen findings to attacker-created GitHub repositories (descriptions reading "Shai-Hulud: Here We Go Again") and over DNS. Treat any environment that installed an affected version (with install scripts enabled) as compromised: rotate and revoke all reachable credentials (npm and GitHub tokens, cloud keys, Vault/Kubernetes secrets, and CI org/repo secrets). Part of the August 2026 npm worm that poisoned 400+ packages across many organizations. Source: amazon-inspector (3494171a4de16e6bdac18f91730981c0dda503db0986f1a1673200bad9777e4a) package.json declares a preinstall hook that runs setup.mjs. setup.mjs is itself javascript-obfuscator-style (renamed identifiers, per-function string dictionaries, indirect property access). It probes for a local `bun` binary and, if absent, downloads a Bun runtime archive from GitHub releases to a temp directory, extracts it, chmods the binary executable, and immediately invokes it via execFileSync against the sibling file math_init.js with the package directory as cwd. math_init.js is a single-line, 727,680-byte file with rotated string-array obfuscation (`_0xXXXX` identifiers, `WV8StW`/`hc1jfK9`-style decoder + array-rotation), and its name does not correspond to any functionality documented for the package (advertised as a Bots API SDK). The alternate-runtime-dropper pattern executes the payload under a freshly-fetched runtime that Node-based scanners do not inspect, and both the loader and the payload are obfuscated. Installing this package causes obfuscated code of unknown behavior to execute automatically on the installer's host before any application code runs.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
